All Marylanders 16 and over can now preregister for vaccination appointments at mass sites, Maryland Gov. Larry Hogan announced at a press conference Thursday.

The announcement comes as both COVID-19 cases and vaccinations are climbing in the state. 

Last month, Hogan said that all Marylanders 16 and older will be eligible for vaccinations by April 27 at the latest.

The state entered Phase 2B on Tuesday, which included Marylanders 16 and older with underlying conditions that could increase the severity of illness.

The state has administered more than 2.7 million vaccine doses, including doses of the two-dose Pfizer and Moderna vaccines, as well as the single-dose Johnson & Johnson shot.

The state will continue to prioritize people who are currently eligible for vaccines but have not yet received them.

Marylanders can preregister for appointments at or by calling 1-855-MD-GOVAX.
